Another of the genre so popular in the seventies :_Degenerated New York locale peopled by degenerates, organized crime, prostitute girlfriends and mentally ill anti-hero who despite barely contained violence is uncorrupted. Oh yeah, and pop music accompanied. This is one of the best. A musical prodigy turned childlike idiot savant whose dexterity in being a strong man for his asshole loan shark father is equal to playing Bach. Dark and intense with a powerful fourth wall breakthrough.
